介绍了一种用于记录自然行走手臂摆动过程中上臂和肩部肌肉动作电位的遥测装置。前摆动是由一些向内的旋转肌的活动引起的，而屈肌保持不活动。三角肌的后部和一些外旋肌是向后摆动的原因。在步行转身过程中，直行过程中不活跃的屈肌发生电活动，这是由于向前摆动的偏移增加，这抵消了躯干的扭转运动。即使在手臂不摆动的情况下，与步幅相关的肌肉活动也会持续。
A telemetering device is described to record action potentials from muscles of the upper arm and the shoulder during the arm swing of natural walking. The forward swing is caused by activity in some inward rotators, the flexors remaining inactive. The posterior part of the deltoid and some outward rotators are responsible for the backward swing. During walk-turning electrical activity occurred in flexors inactive during straight walking accounting for the increased excursion of the forward swing which counteracts the torsional movement of the trunk. Step-related muscular activity persisted even when the arm was prevented from swinging.
